diamond core drilling

Diamond core drilling or "coring" is the process of drilling perfectly round holes through concrete, brick, masonry, stone, and asphalt structures such as walls, floors and ceilings.

Diamond core drills can be operated in any orientation, vertical, horizontal and even inverted (upside down).



A drill bit consists of a steel tube with diamond segments silver soldered or laser welded on the drilling end. The core bits are mounted on the rotating shaft of various types of diamond drillingmachines.

Most diamond drills are connected to a stand that is secured to a wall or floor with an anchor. However, suction units and other methods can be utilised.


Diamond drills can be powered by electricity or hydraulic power sources. Diamond drill bits can range from 10mm to 2mtrs in diameter. Drilling depths are virtually unlimited with the use of continuous feed barrels or by using extension rods. A cylindrical slug or "core" of concrete is removed from the hole after the drilling is complete.
